With that dissatisfaction in mind (which isn’t particularly unusual), take a look at incumbent re-election rates over the years, via Open Secrets:

We’re going to have to do a better job of proving we want to get rid of much of entrenched, snout-in-the-trough Congress. Of course, the power of the incumbency often manages to find ways around the disgruntlement in all sorts of ways (they write the rules). However, more involvement in the primary process would be a good start, but not many people pay attention in those early stages, and then often complain about the lack of good choices on election day.

And some people don’t even pay attention on election day: Check out this detail about the above poll: Five percent were “not sure” which presidential candidate they voted for last year. Nice.
